RAILWAY'TRUCK.

SPECIFICATIN forming part of Letters Patent No. 723,430, dated lVlarchv 24, 1909i.

Application filed October 29, 1902.' Serial No. 129.298. (No model.)

To @ZZ whom t may concern:

Be it known that we, HERBERTW. WOLFF and ARTHUR LIPSCHUTZ,citizens of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement 'in Railway-Trucks, of which the following is a full,- clear, and exact description, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a plan view of one end of our improved truck, partly broken away. Fig.

2 is a similarview looking toward one end of the bolster, and Fig. 3 is a view showing one side of the bolster and connected parts.

This invention relates to railway-trucks composed of metal; and it consists in certain details in the construction and arrangement thereof, all as hereinafter more fully described, and particularly pointed out inthe claims.

Referring` to the drawings, A represents the car-wheels, B the bolster, B the centerplate, C the bolsterfspring, D the bolster-' spring seat, D5 the bolster-spring cap, E the upper arch-bar of the truck-frame, F the inverted arch-bar, and G the tie-bar thereof, all of which except saidspring-seat may be of the usual type incident to-structures of this class. Y

It will be noted by reference to Fig. 3 that the lower arch-bar is formed of a channel:

and that the column .guide-bar H (hereinafter called column) rests thereon at its lower end, where said column is provided with the the lower arch-bar is a bolster-spring seat lj, comprising the supporting-plate D', vertical members D2, and top plate D3, upon which latter rest the bolster-springs C.. At each end of said spring-seat is provided a seat D4, in which is held one end of an angle K, which latter is secured in position by means of bolts L, passing through the lateral flanges H of the column, thence through said angle and the end walls D2 of said seat D, where said bolts are provided with heads, While nuts L' and keys L2 serve to hold said bolts firmly in position.

The angles K referred to extend across the truck and are provided at convenient intermediate points with tie-plates K/ and K2, the former being generally located substantially in line with the wheels, the latter about midway the length of said angles and said latter plate being somewhat Wider than the Others, whereby said angles are firmly secured together. The use of said angles enables us .to dispense with the usual spring-plank incident to structures ot this class and permits ,of much. lighter construction than where a wide and continuous single member is used at this point. l

The skeleton spring-seatshownin addition to the vertical members D2 has integral therewithrthe reinforcing-webs d, which serve to strengthen the structure and aid in supporting the springs, bolster, and weight carried thereby.

We are aware that minor changes in the construction, arrangement, and combination of the several parts of our truck can be made and substituted for those herein shown and described withoutin the least departing from the nature and principle of our invention.

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is

1. In a railway-truck, angles, spring-seats resting on said angles and columns connected with said seats and angles by fastening means passing through vertically-disposed portions of said columns,angles and spring-seats; substantially as described.

2. In a railway-truck, a skeleton spring as described.

5. In a railway-truck,springseats provided with seats, angles resting in said seats, columns, and securing means passing horizontally through said columns, angles and seats whereby said members are secured together; substantially as described.

6. In a railway-truck,spring-seats provided with seats for angles, angles in said seats with their vertical members at the ends of said spring-seats, columns in proximity thereto andconnected with said angles by the same with seats for angles, angles in said seats with their vertical members at the ends of said spring-seats, columns in proximity thereto, lateral flanges on said columns, said seats, angles and the anges of said columns being secured in position by the same fastening means; substantially as described.

8. In a railway-truck, skeleton spring-seats comprising a supporting-plate, vertical members and top plate, and angles secured thereto by means passing through one of the Walls of said skeleton; substantially as described.

9. Ina railway-truck, skeleton spring-seats comprising a supporting-plate, vertical members and top plate, and angles secured thereto by means passing through the Vertical Walls of said skeleton; substantially as described.

In testimony whereof We hereunto affix our signatures, in the presence of two Witnesses, this 24th day ot' October, 1,902.
